[Same period] Yang Lei, Deputy Director of Flood and Drought Disaster Prevention Department of Wuhan Municipal Water Affairs Bureau

　　Ready to take off, the flight distance is one kilometer and the pilot takes off.

　　[Commentary] On July 16, Yang Lei, deputy director of the Flood and Drought Disaster Prevention Division of the Wuhan Municipal Water Affairs Bureau, sat in the headquarters and dispatched three drones to carry out patrols. At the order of three orders, three drones took off gradually on the platform on the 9th floor of the Office of the Flood Control and Drought Relief Headquarters of Wuhan City, flying in the direction of the target. At the same time, in the command room on the 5th floor, the pictures taken by the drone are transmitted to the large screen in real time.

　　[Commentary] Yang Lei introduced that since the flood season this year, the Wuhan Water Affairs Department has formed a drone team to participate in patrol inspections, personnel search and rescue, and launched a real-time drone live broadcast platform. The live video is transmitted back to the command center, and more than 1,000 sets have been used so far.

　　[Same period] Yang Lei, Deputy Director of Flood and Drought Disaster Prevention Department of Wuhan Municipal Water Affairs Bureau: Actually, the drone is actually not new. In fact, we used it in the flood control in Wuhan in 2016. In 2016, we divided the flood in Niushan Lake It has actually been used, but at that time it was different from the current one. At that time, our pilot needed to go to the scene to fly, then copy the video back to our command room, and then give the expert leader to make a decision to watch. This time It is relatively lagging, but our platform is different now. Now everyone sees that our platform is now transmitted back in real time.

　　[Explanation] Yang Lei said that in terms of inspection efficiency, the UAV inspection radius is about 8 kilometers, which is more efficient than walking inspection.

　　[Same period] Yang Lei, Deputy Director of Flood and Drought Disaster Prevention Department of Wuhan Municipal Water Affairs Bureau: It is definitely better than manual inspections. One is that it is much better in scope and speed. What we differ from this year is that we are in various risk segments There are also emergency rescue teams and preparation points around. If a dangerous situation occurs, experts will quickly judge and immediately notify us that our emergency rescue team will immediately.

　　[Commentary] Yang Lei said that the next step is to incorporate multiple UAV live broadcast systems into the construction of smart water services. After the system is mature, it can also be extended to fire protection, emergency, traffic control, urban management and other departments to improve the level of urban governance.
